External battery control via Modbus (TCP)
1 | External energy management system (e.g. energy supply company) |
2 | Control via Modbus (TCP) |
3 | Control electronics of the inverter |
If external battery control via Modbus (TCP) is selected, the inverter receives the control signals for charging and discharging the connected battery via Modbus (TCP).
To do this, the inverter must be connected to the internet via Ethernet (LAN).
The internal energy management remains active, but is overridden by the external specifications regarding charging and discharging power.
The following commands are possible:
- Charging/discharging the battery via current specification in percent or watts
- Charging/discharging the battery via power specification in percent or watts
- Range specification of a min./max. SoC in percent
If external control signals are not received for a longer period of time, the inverter returns to internal battery control. The time specification for this is set in the web server. The specifications of the external provider must be observed.
Activating external battery control via Modbus (TCP)
The inverter must be connected to the local LAN network.
- Start an Internet browser on the computer.
- Call up the web server of the inverter.
To do this, enter the inverter IP address in the address bar of the Internet browser and confirm with ENTER. The IP address can be read on the inverter display. - The web server page opens.
- Log in to the web server as an installer.
- Select the menu item Battery > Battery settings.
- The Battery settings page opens.
- Under Battery control, select the function External via Modbus protocol (TCP).
- Click on the Save button.
- The function is now active.
